WILLIAM H. PINK, or DIAGONAL, IOWA.

RECORD-REPEATING DEVICE.

To all whom it may concern:

Be it known that I, WILLIAM H. FINK, a citizen of the United States, and a resident of Diagonal, in the county of Ringgold and State of Iowa, have invented a certain new and useful Record-Repeating Device, of which the following is a specification.

The object of my invention is to provide a device of simple, durable, and inexpensive construction which will efiiciently move the tone arm of a phonograph after arecord has been played to its starting position for repeating the playing of the record without interfering with the ordinary use of the phonograph and without injury to the record.

A further object is to provide such a de vice including a disk or wheel having a flat portion in its periphery, and balanced by means of weights or the like causing the wheel to stand in position with the flat portion away from the disk, which device has coacting parts including means for holding the wheel or disk in position with the flat portion above the record, and a device adapted to be engaged by the moving tone arm when the record has been played for releasing said holding means, and which device also has means adapted when the holding means is released and the wheel rotates to its normal position to be actuated by the rotation of the wheel in contact with the disk for lifting the tone arm and moving It to starting position, and lowering it to playing position.

A further object is to provide such a device which may be swung out of the way when desired.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which- Figure 1 is a top or plan view of a phonograph equipped with a repeating device embodying my invention.

Fig. 8 shows a detail View of a portion of the disk or wheel.

Fig. 9 shows a detail view of one of the pivoting devices.

In the accompanying drawings I have used the reference numeral 10 to indicate generally the phonograph cabinet, above which is supported the ordinary rotatable turn-table 11, on which is a phonograph record 12. 1

Sup orted on the cabinet 10, and spaced from t e turn-table 11 is a base 13, shown in Figs. 1, 3, 7 having an upwardly extending post 14, particularly illustrated in Fig. 7.

The post 14 is provided at its upper end with a cam face 15.

A downwardly opening supporting sleeve 16 is extended downwardly over the post 14, as shown in Fig. 7, and has mounted in its upper end a screw 17 which bears against the cam face 15, as illustrated.

The sleeve 16 is provided near its lower end with a casing 18 in which is mounted a short spindle or shaft 19, on which is an eccentrically mounted disk 20 forming a locking member.

On one end of the shaft 19 is a'handle 21; by adjusting the handle 21 to one position the high part of the disk 20 may be caused to grip the upright 14, by turning the handle 21 to another position and thus rotating the shaft 19 and the disk 20, the high part of the disk 20 may be moved away from the upright for unlocking the upright from the sleeve 16. Connected with the upper end of the sleeve 16 is a horizontally extending bar 22 having at its end spaced from the sleeve 16a substantially horizontal arm 23 inclined away from the bar 22 as illustrated in Fig. 1.

The outer end of the arm 23 supports a 'portion 26 forming part of its periphery.

On what I may call the rear side of the wheel or disk 25 is a cam 27 which also serves as a weight tending to normally hold the wheel 25 in position where the flattened the teeth 35 after the i 54. On the bar 22 is a bracket 55.

portion 26 will not be immediately above the record 12. Just above the bar 22 is a bar 28 having one end 29. extended away from the bar 28 and forming a bearing for a s indle 30 on one end of a shaft 31. The 0t er end 32 of the bar 28 extends away from said bar and forms a bearing for the-spindle 33 formed at the other end of said shaft 31.

The bar 28 is supported on the bar 22 in the following manner. On the bar 22 are secured spaced upwardly extending bracket arms 28 which have at their upper ends spindles 28 The spindles 28 are journaled in the ends 29 and- 32.

The end 32 projects beyond the shaft31, as clearly illustrated in Figs. 3 and 4, and carries a roller 34 arranged to contact with the cam 27. J

The wheel or disk 25 is provided with inturned teeth 35 formed on the interior of the flange or the like 36. For a short portion of its interior the flange 36 is not provided with said teeth, as illustrated at 37.

On the end of the spindle 33 is a small gear 38 which meshes with the teeth 35.

Secured to the wheel 25 adjacent to one end of the clear portion 37 of the flange 36 is a'curved flat spring 49 having at its end a substantially right-angled extension 50,

so arranged that when the wheel 25 is rotated and the gear 38 reaches the curved portion 37, it-will slide against the spring 49 until. it reaches the extension 50 which will engage the teeth of the gear 38 and hold said gear in such position as to accurately mesh with gear has cleared the clear portion 37.

On the shaft 31 is a spiral device 51, which may be made integral with said shaft, or ma have the form of a wire wound on said aft. 4

Slidablymounted on the shaft 31 is a stop device 52which may be locked on said shaft b means of a set-screw 53.

On t e front of thewheel 25 is asto pin ivotallysupported on the bracket 55 is a locking arm 56 having a finger 57 at its end adapte to coact with the pin 54.

Secured to the other end of the locking arm 56. by means of a screw-bolt 58 is a trigger arm 59 having at its free end an upwar ly extendin finger 60.

The trigger arm 59 is adjustably connected with the locking arm 56 by means of a screw-bolt 58 and-nut 61, whereby the arms 56 and 59 may be adjustably and rigidly locked together.

A spring 62 connects the trigger arm 59 and the bar 22 and tends to normally hold the locking arm 56 in position where the finger 57 is in the path of travel of the stop pin 54; v

Mounted on the cabinet 10 is the ordinary swinging tone arm64, upon which is supported in the ordinary way the sound box 65. Secured to the sound box 65 by means of a screw or otherwise 66 is a projecting "arm 67 which/extends to position above the shaft 31;

In the practical operation of my improved device, the parts are installed as herein shown and described. a

When the disk or wheel 25 is set for use the stop pin 54 will engage the finger 57 which will hold the wheel in position with the flattened portion 26 downwardly and immediately above the record 12.

The weight, which. in this instance is formed by the cam 27 is so arranged that when the finger 57 is released from engagement with the stop in 54, the disk or wheel 25 will rotate slight y.-

In Fig. 5 I have shown thewheel at thebeginning of such rotation just Y afterthe pin has been released from engagement with the finger 57.

The roller 34 will rest on the cam 27, and

flattened portion 26 is downwardly the arm 67 "will stand spaced above the shaft 31, which will not in any way interfere with the ordinary operation of the finger.

If it is desired to swing the repeater device to position where it will be out of the way, the lock eccentric 20 maybe turned by means of a handle 21 for releasing it the shape of the cam is such that when the y from engagement with ,the upright 14,

whereupon the bar 22 may be swung around. As the sleeve 16 rotates on the upright 19, the shape of the cam 15 is such as to cause the screw 1.7 to travel upwardly for. raising the repeater device somewhat.

Assuming, however, that the parts are in position ready for use with the disk standing above the record, then when the record is playing and the tone arm moves to position where the playin is finished, the arm 67 will engage the ii nger 60 for moving the trigger arm 59 a inst the tension of the spring 62, for re easing the finger 57 from engagement with the stop pin 54, thereupon the wheel 25 will rotate until its periphery engages the record.

The frictional engagement of the moving record with the periphery of the wheel 25 will rotate the wheel 25.

Durlng the first part of such rotatiomthe roller 34 will travel upwardly to the high part of the cam 27 which will cause the raising of the shaft 31, which will engage the arm and lift the sound box.

When the gear 38 reaches the spring 49, the spring 49 will serve to cause the gear 38 to accurately mesh with the gear teeth 35, and thereafter'the gear teeth 35 on the rotating wheel will cause rotation to be imparted to the gear 38 and the shaft 31.

The spiral device ,51 will then engage the arm 67 and swing'the sound box and the tone arm toward position for beginning the playing of a record.

The limit of movement of the tone arm is determined by properly positioning the stop device 52, according to the size of the record being played.

When the wheel 25 has been rotated on revolution to position with the flattened portion 26 downwardly, the finger 57 stands in the path of the pin 54 and will then stop the rotation of the wheel 25.

It will be understood that the spring 62 returns the finger 57 to position for engaging with the pin 54 as soon as the tone arm is moved away from its position where the arm engages the finger 60.

When the wheel 25 has made one revolution the cam will have reached such a point in its movement, that the roller 34 may move downwardly for lowering the arm 67 and thereby lowering the sound box to playing position, and permit thegear to move out of mesh with the teeth 35.

The record will then be played again and the action of the repeater device will be repeated each time at the completion of the playing.

It will be noted that the shape of the cam 27 is such that while the roller 34 is traveling over the high part of the cam, the gear 38 will mesh with the teeth 35, but when the roller 3- reaches the lower part of the cam, said gear will be out of mesh.

Some changes may be made in the construction and arrangement of the parts of my improved repeater device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
